Scientists in the UK have developed a method of genetically modifying and managing aggressive form of the moth, which causes serious damage to cabbage, rapeseed and other crops worldwide.
Scientists at Oxford University, United in the company Oxitec, brought the cabbage moth with a "gene of self-destruction", which essentially reduced the population during the tests in greenhouses.
The efficacy of the gene of self-destruction was already verified in carrying the dengue mosquitoes, whose population was reduced by 90% in trials in Brazil, Panama and the Cayman Islands.
This study opens new possibilities for the future of agriculture with pest control methods that are non-toxic and don't use pesticides, reported researchers at Oxitec.
According to the researchers, whose work was published in the journal BioMed Central Biology, the suppression of Diamondback moth in vegetable farmers producing cruciferous, costs the world's farmers $5 billion a year.
Entomologists at Cornell University in the USA, who collaborated with researchers at Oxitec, said that neither standard nor organic pesticides can't control the spread of the moth. The cabbage moth is a serious problem for farmers in the state of new York and all over the world, producing cruciferous vegetables and field crops. The moth attacks the crop, having developed a resistance to insecticides, so urgently need new ways to control its population.
The researchers genetically modified male moths that can mate exactly the same as ordinary insects, but they reproduce only from males. In tests in the greenhouse room of GM animals in the population of moths resulted complete destruction within eight weeks.
Scientists said that unlike insecticides that can affect a number of insects including bees, the approach of genetic modification is directed to only one specific type of pest.
Gene-destruction non-toxic, so birds and other animals will not get adverse effects from eating a moth.
Independent experts welcomed the success of Oxitec.
Specialists in molecular genetics from the British University of Surrey, said that the results of the research in the field would represent progress environmentally friendly ways to control diseases, insects and improve food production.
Now scientists are planning further studies to test the GM-mole in harsher environmental conditions in the Northern part of the state of new York.
Data from a study already approved by the Ministry of agriculture of the USA, will include field tests this summer.
